I have a Sputnik, and I like certain aspects of the Steamroller quite a bit, but I would get a Salsa Casseroll Single, as long as it fits well. It can take wide tires (roughly the same as the Steamroller) and fenders, the paint job and matching stem look great, quality parts are standard, and it has two (this should be a requirement if you are doing longer rides) water bottle mounts. It is the best off-the-shelf, single speed, road bike under $1000 right now. You can also make it geared if you ever feel like it.
